Description

Pocket / Envelope type cages are used for filter bags that are in the shape of a pocket or envelope. This type of design is mostly used in Asphalt, Boiler or Ferro metal applications where higher air permeability is required. Pocket type cages come in many custom designs. The pocket shape of the cage helps in dividing the bag in three or four parts with precision. These cages are installed horizontally therefore it is important to make the sealing cap of these cages with great precision.
